The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with IsO, also take part in the work. isO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International a vote. International Standard ISO 9189 was prepared by Technical Committee ISO/TC 39,Machine tools. Annex A of this International Standard is for information only. ISO1993 All rights reserved.

Those fea- tures which are not not covered by this International Standard are listed below, and the reason(s) for their exclusion are given. a) Hole in bed and bedplate, and bedplate thickness These directly influence the rigidity of the press and as such are often di- mensioned to suit the production of a specific component. One common practice, which is employed to maintain maximum bed stiffness, is to pitch of the press tooling. b) Height of bedplate from floor The use of automatic feeding and unloading mechanisms makes the specification of floor-to-bedplate height undesirable. c) Tool fixing holes and T-slots Owing to the relatively high stroking speed of these presses, the designer always endeavours to minimize the mass of the reciprocating parts. It is usually impracticable to achieve total balance of these masses and as a result the press members will be subjected to high disturbing forces. By specifying the tool fixing holes, the die and press designer would be restricted in achieving the optimum solution for each application. d) Passage through uprights, and strip width These may be standardized at a later date if there is sufficient support for this work. (0 Stroking rate characteristic depends on the specific application of the press (feed length, type of feed; gripper, roller, step 'motor; type of die, length of stroke, feed-out of parts, etc.). Modern high-speed presses can be provided with a variable adjustable stroking rate from 1 to 10. f) Energy The working energy cannot be fixed since the stroking rate is variable over 10 as mentioned in e), the working energy changes at a ratio of 1 to 100. ii Copyright International Organization for Standardization Not for Resale
